Cassin's Hawk-Eagle Spizaetus africanus in Ndundulu Forest: a First Record for Tanzania, with Biogeographical Implications

ABSTRACT A single adult Cassin's hawk-eagle Spizaetus africanus was sighted on five occasions over three years in a highland forest in the Udzungwa Mountains, the first ever record of this species in Tanzania. This discovery has potentially significant biogeographical implications, strengthening ancient links between the forests of the Udzungwa Mountains and the Guineo-Congolian forests of central Africa.
